将邮件和短信/彩信代表添加到类类型中

Question

我有一个简单的应用程序。它通过电子邮件和短信/彩信截图。

由于我有两个按钮，每个按钮执行两个不同的功能 - （1）屏幕截图然后电子邮件; （2）屏幕截图然后短信/彩信，我需要将它们添加到代码中的class中。

现在。。。

import UIKit
import MessageUI

class ViewController: UIViewController, MFMailComposeViewControllerDelegate {

如何将MFMessageComposeViewControllerDelegate添加到上述类语句中？

我想我需要，因为我有发送电子邮件和短信/彩信的功能。

对我的语言描述表示歉意，我是新手:)

import UIKit
import MessageUI
class ViewController: UIViewController, MFMessageComposeViewControllerDelegate, MFMailComposeViewControllerDelegate {
@IBOutlet weak var phoneNumber: UITextField!
override func viewDidLoad() {
    super.viewDidLoad()
}
@IBAction func sendText(sender: UIButton) {
    if (MFMessageComposeViewController.canSendText()) {
        let controller = MFMessageComposeViewController()
        controller.body = "Message Body"
        controller.recipients = [phoneNumber.text]
        controller.messageComposeDelegate = self
        self.presentViewController(controller, animated: true, completion: nil)
    }
}

   func messageComposeViewController(controller: MFMessageComposeViewController!, didFinishWithResult result: MessageComposeResult) {
    //... handle sms screen actions
     self.dismissViewControllerAnimated(true, completion: nil)
    }
override func viewWillDisappear(animated: Bool) {
    self.navigationController?.navigationBarHidden = false
}
 @IBAction func sendMail(sender: UIButton)
 {
    let mailClass:AnyClass?  =NSClassFromString("MFMailComposeViewController")
   if(mailClass != nil)
   {
    if((mailClass?.canSendMail()) != nil)
    {
      displayComposerSheet()
    }
  }
  func displayComposerSheet()
  {
   let picker: MFMailComposeViewController=MFMailComposeViewController()
   picker.mailComposeDelegate=self;
   picker .setSubject("Test")
   picker.setMessageBody("Mail Sharing !", isHTML: true)
   let data: NSData = UIImagePNGRepresentation(UIImage(named: "images.jpg")!)!
   picker.addAttachmentData(data, mimeType: "image/png", fileName: "images.png")
   self.presentViewController(picker, animated: true, completion: nil)
  }

  func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {
    switch result.rawValue {
    case MFMailComposeResultCancelled.rawValue:
        print("Mail cancelled")
    case MFMailComposeResultSaved.rawValue:
        print("Mail saved")
    case MFMailComposeResultSent.rawValue:
        print("Mail sent")
    case MFMailComposeResultFailed.rawValue:
        print("Mail sent failure: (error!.localizedDescription)")
    default:
        break
    }
    controller.dismissViewControllerAnimated(true, completion: nil)
  }
